Thermodynamically-Consistent Modeling of Ferromagnetic Hysteresis
WebJun 14, 2024 · 1. Accurate modelling of the hysteretic behavior of ferromagnetic materials is a topic of huge commercial interest because of their role in transformers, motors, and generators. There exists a huge … Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become magnetized. Once magnetized, the magnet will stay magnetized … See more The phenomenon of hysteresis in ferromagnetic materials is the result of two effects: rotation of magnetization and changes in size or number of magnetic domains. In general, the magnetization varies (in direction … See more Magnetic hysteresis can be characterized in various ways. In general, the magnetic material is placed in a varying applied H field, as induced by an electromagnet, and the resulting See more There are a great variety in applications of the theory of hysteresis in magnetic materials. Many of these make use of their ability to retain a memory, for example magnetic tape See more The most known empirical models in hysteresis are Preisach and Jiles-Atherton models. These models allow an accurate modeling of the hysteresis loop and are widely used in the industry. However, these models lose the connection with … See more • Degaussing See more WebFerromagnetic hysteresis Abstract: An equation describing the initial magnetisation … miniature microphone stand
